Abstract (en)
[origin: WO2020234819A1] A testing machine (1) for a vehicle wheel (4) comprises a base frame (2), suitable for resting on a support surface (P), and a rotating drum (3) rotatably supported by the base frame around a drum axis (T). The testing machine (1) further comprises rotating drum actuating means (5), for rotating the rotating drum (3) around the drum axis (T), and a wheel movement device (6), suitable for rotatably supporting the vehicle wheel (4) around a wheel axis (Z) and for moving the vehicle wheel (4) from a position spaced from the rotating drum (3) to a position in contact with the rotating drum (3). The wheel movement device (6) is rotatably supported by the base frame (2) around a slip rotation axis (S), incident or perpendicular to a plane (K) tangent to the contact point (Q) between the vehicle wheel (4) and the rotating drum (3). Moreover, the wheel movement device (6) is rotatably supported by the base frame (2) around a camber rotation axis (C), perpendicular to the wheel axis (Z) and to the slip rotation axis (S), so that following a rotation of the wheel movement device (6) around the camber rotation axis (C), the vehicle wheel (4) is rotated according to a camber angle (β).
